Tijoux dont stress yourself even if you didnt meet your targets in life dont look at those above you.Like the ones who have achieved /accomplished more than you.Be it having a family,better paying job etc.At times you need to look at those below you their are people very sick and are bed ridden,some people have marital issues,some have no parents alive,some have very low income paying jobs and are supporting a family that is the size of a football team.
So dont look at the materials in life and compare yourself with them.Because you dont know what people who have "accomplished" more than you are going through.Money doesnt buy happiness.
You need to count the blessings Allah has given you and be thankful so that he can increase and bless it.I have seen people that are very rich and depressed and poor people that are contented in life.
Success is a relative word.Success according to Islam doesnt mean being famous, wealthy,good looking,having come from a good family,having a beatiful wife or having degrees,masters or a Phds etc.
Success in this world is finding Allah,Knowing Allah,Knowing his rights on you and appreciating his blessings upon you and trying to strive to appease him.At the end of the day life.is temporary.
Lastly give out charity alot for very charity will change your life.Also change your friends,Visit your family often if you have parents serve them well and be kind.always visit them and put a smile on their face.They dont need money at times all they need is yo see you.
Also learn your religion,make dikr do alot of istighfar.
There was a time Hassan AlBasri was with his students and a man came he said he didnt have kids and the Sheikh told him to do istighfar,another came alittle later asked him that his crops keep failing because of no rains he told him to do istighfar.
Then when he left the students asked Hassan ehy each time he was giving the same answer even though they jad different problems.
He said its not my word but the words of the quraan " Tell them to seek for forgiveness from their Lord,for veryly he is oft forgiving,He he will send rain upon them and he would bless him with sons and daughters,and would bless them with gardens( that have produce) and rivers......"
Lastly may Allah ease our situations, bless our provisions and guide us to the right path.
Ameen.
